Heatwave Henry?

Extreme heat already kills more Americans than do hurricanes and tornadoes combined. Heatwaves are, however, largely silent killers, with effects that are often only apparent afterwards. There is often a vast undercount of the mortalities, that follow extreme heat. Raging fires are newsworthy but the more insidious effects of heat, are less so. California is now being advised to give heatwaves names, like those allocated to hurricanes and storms (https://www.theguardian.com/environment/2022/feb/28/california-heatwaves-naming-system-climate-crisis). Clearly, extreme heat events are now occurring more frequently and intensely in many parts of the US. People exposed to heatwaves may die of kidney or heart failure, well after the event itself. Exposed folk can be encouraged to take steps to reduce their risk. Giving heatwaves names, may be helpful in passing on this advice. It may also help impress on people the likely severity of a predicted heatwave. It wouldn't be a bad idea to consider naming heatwaves in other parts of the globe.
